Symptom Checklist-90 (SCL-90)
90-question symptom check covering 9 dimensions — a broad mental health screening tool.
How are you really doing - across all dimensions of mental health? The SCL-90 covers 90 symptoms across 9 domains: somatization, OCD, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. About 15-20 minutes. Broad psychological symptom assessment, not a targeted diagnostic tool.
How are you really doing — across all dimensions?
Sometimes a single-domain test does not cut it. You might be feeling anxious and depressed and having trouble sleeping and feeling on edge around others. That is when a broader screening tool makes more sense.
The SCL-90 covers 90 symptoms across 9 domains: somatization, obsessive-compulsive tendencies, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. It has been in clinical use since the 1970s.
Each item asks how much a particular symptom has bothered you over the past week, on a 5-point scale. The result gives you three global indices — the most commonly used is the Global Severity Index (GSI), which averages all 90 items into a single distress score.
This is not a diagnostic tool. Elevated scores just point you toward areas that might need a closer look with a more targeted instrument.
Scoring Guide
90-item self-report symptom inventory covering 9 dimensions: Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic Anxiety, Paranoid Ideation, and Psychoticism. Each item rated 0-4. Three global indices: GSI (average), PSDI (intensity), and PST (symptom count). Clinical cutoff commonly set at GSI >= 0.58 for psychiatric screening reference.Result Interpretation
Finish the 90 questions and you get your results straight away — no account, no sign-up, no waiting.
We calculate your total from your answers, then give you a plain-language explanation of what the numbers mean. Where a test has sub-scales, each dimension gets its own score. Whenever possible, we also show how your results compare to population norms.
